Patented Apr. 1, 1930 UNHTED STATES PATENT OFFICE WILLIAM E. STEVENS AND CHARLES B. JAY, OF RAYMOND, WASHINGTON; SAID STEVENfS ASSIGNOR TO RAY SAYLES ROLLER SCREEN Application filed. April 21, 1927.

The invention is a screen for windows or the like, which is permanently attached to the outside of the window, which may be readily opened and closed and which is positively fly proof.

The object of the invention is to provide a fly proof window screen which is permanently attached and in which the tenson of a roller upon which the screen is wound may readily be adjusted from the exterior of a casing in which the screen may be mounted.

Another object of the invention is to provide a screen for windows or the like which is permanently attached to the outside of the 5 window and at the same time readily opened and closed.

Another object of the invention is to provide a roller screen with a casing to inclose the screen to protect it from the weather.

A further object of the invention is to provide a roller screen having means for adj usting the tension on the roller.

And a still further object of the invention is to provide a roller screen which is of a d simple and economical construction.

With these ends in view the invention embodies a spring roller a screen upon the roller, a casing having a slot in the lower side in which the spring roller is mounted, means for adjusting the roller from the exterior of the casing, vertical guides extending downward from the ends of the casing to hold the edges of the screen, and means for holding the screen downward.

Other features and advantages of the invention will appear from the following description, taken in connection with the drawings, wherein:

Figure 1 is a front elevation showing a part of a window frame with the device in place.

Figure 2 is a cross section through the roller casing.

Figure 3 is a cross section through the clip at the lower edge of the screen.

Figure 4 is a longitudinal section through the roller.

Figure 5 is a cross section through one of the vertical guides.

Figure 6 is a view showing the construction at one end of the roller casin g.

Serial No. 185,437.

Figure 7 is a view looking at the under side of one end of the roller casing showing a notch through which the edge of the screen passes.

Figure 8 is a cross section through the spring roller.

In the drawings the device is shown as it would be made wherein numeral 1 indicates the spring roller, numeral 2 the roller casing, and numeral 3 the screen.

The roller 1 is made of a tubular shaped piece of material with a lap joint as indicated'by the numeral 4 in one side and in which the upper end of the screen 3 is held as shown in Figure 8. At the ends of the roller are sleeves 5 and 6 which support the ends of a shaft 7 as shown. One end of the shaft which is indicated by numeral 8 is of a smaller diameter so that a shoulder is provided with bears against a washer 9 which bears against the sleeve 6, and it will also be observed that one side of the sleeve 6 is provided with a recess 10 in which one end of a spring 11 is held by a pin 12. The opposite end of the shaft 7 is provided with a fiat section 14 which is held in a slot 15 in the end of the roller casing to prevent the shaft turning. It will be observed that the slot 15 is provided with a notch 16 so that the shaft 7 may be slightly raised and turned if desired. The outer end of the shaft is provided with a handle 17 by which the shaft may be turned to adjust the tension on the spring. The outer end of the casing may also be provided with an outer freely mounted plate 18 as shown in Figure 6 which has an inverted slot 19 similar to the slot 15 which is used to close the slot 15 and practically seal the end of the casing. The plate 18 is freely mounted so that it will readily raise with the handle 17 and may be held with the notch 19 corresponding with the notch 16 in which position the handle may be readily rotated to adjust the tension of the spring.

The casing be provided with a base plate 20 having the lower edge bent upward as shown at the point 21 which will provide a rounded edge so that it will not cut the screen. An outer shell 22 is attached to the base plate and the lower edge of the outer shell is also bent backward as shown at the point 23 so that a rounded edge will be presented to the screen. The lower portion of the shell 22 extends outward at the ends to form flanges 24 which may be attached to the upper ends of vertical guides 25.

The guides 25 are constructed as shown in Figure 5 and provided with a pocket 26 having rounded edges 27 at the opening thereof and it will be observed that a head 28 at the edge of the screen is slidable in the pockets 26. The head 28 is preferably formed of a flexible insulated wire such as is normally used for electric currents and this wire is woven into the edges of the screen 3 as shown in Figure 5. It is understood however that any other suitable'device may be used to form a bead at the edges of the screen. The lower edge of the roller casing is provided with a notch 29 adjacent each end through which the bead passes.

At the lower edge of the screen is a clip 30 in which the edge of the screen is held as shown in Figure 3. This clip extends across the screen and is provided with short clips 31 by which the screen may be held downward by attachments 32. The attachments 32 may be of any suitable type and may be prm'ided with bolts 33 which are adiustably held in brackets 3d and which have wing nuts 35 which may be screwed downward to hold the clips 31, as shown in Figure 3.

It is understood that changes may made in the construction without departing from the spirit of the invention. One of which changes may be in the design of the roller, another may be in the design of the roller casing or in the use of other means for mounting the roller, and still another may be in the use of other means for holding the screen.

The construction will readily be understood from the foregoing description. To use the device it may be installed on a window frame as shown and it will be observed that when not in use the screen will remain in the casing so that it will not be exposed to the weather and when it is desired to use the screen the screen may be drawn downward by the clip 30 and held downward by the clip as shown in Figure 3. It will be observed that the edges of the screen are completely closed as the beads 28 travel in the guides 25. This therefore provides a permanently attached screen which may readily be opened and which is positively fly proof.

Having thus fully described the invention what we claim as new and desired to secure by Letters Patent, is:

In a roller screen of the character de scribed having a spring roller, a wire screen mounted upon the said roller, suitable guides for slidably holding the edges of the said screen, and means at the lower ends of the said guides for holding the said screen down- Ward; a spring roller tensioning device comalso having an enlarged notch therein, and a handle extending from the end of said roller through the slots in the end of the casing and movable plate.

In testimony whereof we affix our signatures.
